Bird flu virus found in Los Angeles County wastewater

Los Angeles County health officials said they have detected H5N1 bird flu virus in wastewater collected from the A.K. Warren Water Resource Facility in Carson.

The viral “hit” was detected on Oct. 28 by WastewaterSCAN, an infectious disease monitoring network run by researchers at Stanford, Emory University and Verily, Alphabet Inc.’s life sciences organization.

Hits were also seen during the last week in San José, Redwood City, San Francisco, Palo Alto, Sacramento, Santa Cruz, Marina and Turlock.

The Carson plant processes wastewater from roughly 50% of L.A. County’s population, said Annabelle de St. Maurice, the L.A. County Department of Public Health’s director of community outbreak and syndromic surveillance.

Officials say they have not identified the source of the virus, but suggested a few possibilities, including discarded contaminated animal products and infected wild bird droppings. They are also “actively engaging key risk groups,” including dairy and meat-processing sites nearby.

“The likely sources more likely appear to be from animal products, rather than wild birds,” De St. Maurice said.

She said the risk to the public remains low.

H5N1 bird flu has been detected in 203 California dairy herds since August; 17 dairy workers have also been infected. Across the nation, 41 people have been infected — 21 from dairy cows, 19 from poultry and one unknown. The USDA has reported 404 positive dairy herds in 14 states. This number does not include eight herds detected earlier this week in Utah.

It’s also been conclusively detected in a pig from Oregon.

De St. Maurice said the county routinely monitors and tests symptomatic birds, pets and wild mammals.

In addition, she said, the county is working within the community to subtype flu specimens collected in health clinics and hospitals specimens “to see if there are potential H5N1 human cases.”

She noted the county’s public health department is also doing “outreach and education to communities that are at risk,” but said that, so far, there have been no human cases.

De St. Maurice said it was this kind of work — subtyping flu specimens — that enabled Missouri health officials to identify an H5N1 human case that had no reported dairy or poultry contact. The source of that person’s infection has still not been determined.

The wastewater findings come as the virus spreads in California’s dairy cows — which now make up more than half the nation’s reported cattle infections — and as fall migration of wild birds from the Arctic moves south along the Pacific Flyway.

There are now two strains of H5N1 bird flu circulating in California. The form circulating in dairy cows is known by scientists as B3.13. A new wild bird version, which has emerged only recently, is known as D1.1 or D1.2.

Genetic sequencing of the H5 virus found in Los Angeles County wastewater has not been conducted. According to De St. Maurice, the way the samples are captured and identified does not allow for sequencing.

H5 viruses are of bird origin; they are not human viruses.

In a statement, officials said people could reduce their risk of infection by avoiding raw milk, raw cheese and undercooked meats. Pasteurization and adequate cooking inactivates the virus.

They also recommend that people avoid unprotected contact with sick or dead animals, and avoid materials contaminated with bird feces. Pets can also be infected in these ways. And officials request that people report sick or dead birds to local animal control agencies.

They also recommend that people get the annual flu shot. Though the seasonal flu vaccination won’t prevent bird flu infection, it reduces the chances for the bird flu to combine with a human flu — potentially creating a new virus that could spread more easily among people.

Cluster of farmworkers diagnosed with rare animal-borne disease in Ventura County

Cluster of farmworkers diagnosed with rare animal-borne disease in Ventura County

A cluster of workers at Ventura County berry farms have been diagnosed with a rare disease often transmitted through sick animals’ urine, according to a public health advisory distributed to local doctors by county health officials Tuesday.

The bacterial infection, leptospirosis, has resulted in severe symptoms for some workers, including meningitis, an inflammation of the brain lining and spinal cord. Symptoms for mild cases included headaches and fevers.

The disease, which can be fatal, rarely spreads from human to human, according to the U.S. Centers for Disease Control and Prevention.

Ventura County Public Health has not given an official case count but said it had not identified any cases outside of the agriculture sector. The county’s agriculture commissioner was aware of 18 cases, the Ventura County Star reported.

The health department said it was first contacted by a local physician in October, who reported an unusual trend in symptoms among hospital patients.

After launching an investigation, the department identified leptospirosis as a probable cause of the illness and found most patients worked on caneberry farms that utilize hoop houses — greenhouse structures to shelter the crops.

As the investigation to identify any additional cases and the exact sources of exposure continues, Ventura County Public Health has asked healthcare providers to consider a leptospirosis diagnosis for sick agricultural workers, particularly berry harvesters.

Rodents are a common source and transmitter of disease, though other mammals — including livestock, cats and dogs — can transmit it as well.

The disease is spread through bodily fluids, such as urine, and is often contracted through cuts and abrasions that contact contaminated water and soil, where the bacteria can survive for months.

Humans can also contract the illness through contaminated food; however, the county health agency has found no known health risks to the general public, including through the contact or consumption of caneberries such as raspberries and blackberries.

Symptom onset typically occurs between two and 30 days after exposure, and symptoms can last for months if untreated, according to the CDC.

The illness often begins with mild symptoms, with fevers, chills, vomiting and headaches. Some cases can then enter a second, more severe phase that can result in kidney or liver failure.

Ventura County Public Health recommends agriculture and berry harvesters regularly rinse any cuts with soap and water and cover them with bandages. They also recommend wearing waterproof clothing and protection while working outdoors, including gloves and long-sleeve shirts and pants.

While there is no evidence of spread to the larger community, according to the department, residents should wash hands frequently and work to control rodents around their property if possible.

Pet owners can consult a veterinarian about leptospirosis vaccinations and should keep pets away from ponds, lakes and other natural bodies of water.

Political stress: Can you stay engaged without sacrificing your mental health?

Political stress: Can you stay engaged without sacrificing your mental health?

It’s been two weeks since Donald Trump won the presidential election, but Stacey Lamirand’s brain hasn’t stopped churning.

“I still think about the election all the time,” said the 60-year-old Bay Area resident, who wanted a Kamala Harris victory so badly that she flew to Pennsylvania and knocked on voters’ doors in the final days of the campaign. “I honestly don’t know what to do about that.”

Neither do the psychologists and political scientists who have been tracking the country’s slide toward toxic levels of partisanship.

Fully 69% of U.S. adults found the presidential election a significant source of stress in their lives, the American Psychological Assn. said in its latest Stress in America report.

The distress was present across the political spectrum, with 80% of Republicans, 79% of Democrats and 73% of independents surveyed saying they were stressed about the country’s future.

That’s unhealthy for the body politic — and for voters themselves. Stress can cause muscle tension, headaches, sleep problems and loss of appetite. Chronic stress can inflict more serious damage to the immune system and make people more vulnerable to heart attacks, strokes, diabetes, infertility, clinical anxiety, depression and other ailments.

In most circumstances, the sound medical advice is to disengage from the source of stress, therapists said. But when stress is coming from politics, that prescription pits the health of the individual against the health of the nation.

“I’m worried about people totally withdrawing from politics because it’s unpleasant,” said Aaron Weinschenk, a political scientist at the University of Wisconsin–Green Bay who studies political behavior and elections. “We don’t want them to do that. But we also don’t want them to feel sick.”

Modern life is full of stressors of all kinds: paying bills, pleasing difficult bosses, getting along with frenemies, caring for children or aging parents (or both).

The stress that stems from politics isn’t fundamentally different from other kinds of stress. What’s unique about it is the way it encompasses and enhances other sources of stress, said Brett Ford, a social psychologist at the University of Toronto who studies the link between emotions and political engagement.

For instance, she said, elections have the potential to make everyday stressors like money and health concerns more difficult to manage as candidates debate policies that could raise the price of gas or cut off access to certain kinds of medical care.

Layered on top of that is the fact that political disagreements have morphed into moral conflicts that are perceived as pitting good against evil.

“When someone comes into power who is not on the same page as you morally, that can hit very deeply,” Ford said.

Partisanship and polarization have raised the stakes as well. Voters who feel a strong connection to a political party become more invested in its success. That can make a loss at the ballot box feel like a personal defeat, she said.

There’s also the fact that we have limited control over the outcome of an election. A patient with heart disease can improve their prognosis by taking medicine, changing their diet, getting more exercise or quitting smoking. But a person with political stress is largely at the mercy of others.

“Politics is many forms of stress all rolled into one,” Ford said.

Weinschenk observed this firsthand the day after the election.

“I could feel it when I went into my classroom,” said the professor, whose research has found that people with political anxiety aren’t necessarily anxious in general. “I have a student who’s transgender and a couple of students who are gay. Their emotional state was so closed down.”

That’s almost to be expected in a place like Wisconsin, whose swing-state status caused residents to be bombarded with political messages. The more campaign ads a person is exposed to, the greater the risk of being diagnosed with anxiety, depression or another psychological ailment, according to a 2022 study in the journal PLOS One.

Political messages seem designed to keep voters “emotionally on edge,” said Vaile Wright, a licensed psychologist in Villa Park, Ill., and a member of the APA’s Stress in America team.

“It encourages emotion to drive our decision-making behavior, as opposed to logic,” Wright said. “When we’re really emotionally stimulated, it makes it so much more challenging to have civil conversation. For politicians, I think that’s powerful, because emotions can be very easily manipulated.”

Making voters feel anxious is a tried-and-true way to grab their attention, said Christopher Ojeda, a political scientist at UC Merced who studies mental health and politics.

“Feelings of anxiety can be mobilizing, definitely,” he said. “That’s why politicians make fear appeals — they want people to get engaged.”

On the other hand, “feelings of depression are demobilizing and take you out of the political system,” said Ojeda, author of “The Sad Citizen: How Politics is Depressing and Why it Matters.”

“What [these feelings] can tell you is, ‘Things aren’t going the way I want them to. Maybe I need to step back,’” he said.

Genessa Krasnow has been seeing a lot of that since the election.

The Seattle entrepreneur, who also campaigned for Harris, said it grates on her to see people laughing in restaurants “as if nothing had happened.” At a recent book club meeting, her fellow group members were willing to let her vent about politics for five minutes, but they weren’t interested in discussing ways they could counteract the incoming president.

“They’re in a state of disengagement,” said Krasnow, who is 56. She, meanwhile, is looking for new ways to reach young voters.

“I am exhausted. I am so sad,” she said. “But I don’t believe that disengaging is the answer.”

That’s the fundamental trade-off, Ojeda said, and there’s no one-size-fits-all solution.

“Everyone has to make a decision about how much engagement they can tolerate without undermining their psychological well-being,” he said.

Lamirand took steps to protect her mental health by cutting social media ties with people whose values aren’t aligned with hers. But she will remain politically active and expects to volunteer for phone-banking duty soon.

“Doing something is the only thing that allows me to feel better,” Lamirand said. “It allows me to feel some level of control.”

Ideally, Ford said, people would not have to choose between being politically active and preserving their mental health. She is investigating ways to help people feel hopeful, inspired and compassionate about political challenges, since these emotions can motivate action without triggering stress and anxiety.

“We want to counteract this pattern where the more involved you are, the worse you are,” Ford said.

The benefits would be felt across the political spectrum. In the APA survey, similar shares of Democrats, Republicans and independents agreed with statements like, “It causes me stress that politicians aren’t talking about the things that are most important to me,” and, “The political climate has caused strain between my family members and me.”

“Both sides are very invested in this country, and that is a good thing,” Wright said. “Antipathy and hopelessness really doesn’t serve us in the long run.”
